If i understand you correctly, you want add alias for AGG,e.g.:
` .select('c, 'b.count over 'w as 'mycount) --> .select('c, 'b.count as
'mycount over 'w)`
but for SQL we add alias to OVER, e.g.:
`SELECT c, count(a) OVER (PARTITION BY c ORDER BY ProcTime() RANGE
UNBOUNDED preceding) as cnt1 from T1`
So I want to be consistent with SQLï¼What do you think?
